Flooding fears have now hit the Fraser Valley with more than 250 homes on evacuation alert in Langley Township.

The melting snowpack has raised water levels in the Fraser River.

Right now, the Mission Gauge shows a depth of 5.5 metres. Officials say if that reaches 6.3 metres, people would be forced out.

The concern is for more homes along unprotected flood plain areas of north west Langley â" Glen Valley, Bray Island and McMillan Island.

A highstream flow advisory was issued for the Fraser River on May 10.

Temperatures are expected to remain high in the coming days, meaning people should prepare for the worst and hope for the best.

âThey should have plans in place and be prepared for an evacuation just in case the water rises as in the projections,â Ramin Seifi, general manager of engineering and community development for the Township of Langley, told Global News Tuesday.

âThis is not an order.â

Osoyoos Lake has levelled off but with more snow melt expected, it is predicted to reach historic highs later this week.

Disaster assistance is available to some homeowners at this time, but itâs limited to primary residences.

âI think weâre going to get very close to the level of â72,ââ International Osoyoos Lake Board of Control member Brian Symonds said. âI think weâre going to be a little over 917 feet (above sea level), give or take a bit. It really will depend on the weather we get.â

The townâs sewer system is no longer at risk of failure.

âAll our water and sewer infrastructure now is in a manageable state,â Osoyoos chief administrative officer Barry Romanko said.

The town also told residents the Osoyoos landfill will be accepting shoreline flood debris at no cost for the next month.
